[Eustice Scrubb] has posted some videos and pictures of a robotic “eye stalk” that he’s building. It looks like the final version is using 3 servos in an arrangement like tendons through a slinky jr. The ping-pong ball on the top has a BlinkM inside it. You can see a video after the break that shows the three servo tendons in motion. The whole thing is controlled by an Arduino and one of his pictures states that it plays mp3s and has an internal pendulum. None of his pictures seem to implicitly state what it is meant to do though.
